The ``-c`` (compact) option provides a mechanism to reduce the size of
a journal by removing (most/all) transactions prior to the specified
serial number. Note: this option *must not* be used while ``named`` is
running, and can cause data loss if the zone file has not been updated

The ``-x`` option causes additional data about the journal file to be
printed at the beginning of the output and before each group of changes.
